Application filed February 20, 1915. Serial No. 9,816.

To all whom it may concern:

Be it known that I, FLETCHER M. HAW- KINS, a citizen of the United States residing at Greenville, in the county of Iiunt and State of Texas, have invented a new and useful Fumigating Apparatus, of which the following isa specification.

This invention relates to fumigating apparatus especially designed for fumigating rooms, for destroying rodents and for like urposes, one of the objects of the invention Being to provide a generator of novel form for the production of sulfur dioxid, said generator having combined with it a means whereby the sulfur fumes may be forced to any point desired, there being additional means combined with the generator for directing fresh air to a person using the fumes for disinfectant purposes.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and .in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without 'departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of the apparatus.

Fig. 2 is a section on line AB Fig. 1.

Fig. 3 is a plan view.

Fig. 4 is a detail View of a modified form of nozzle for use in connection with the apparatus. ac Referring to'the figures by characters of reference 1 designates a stove or furnace of any desired size and proportions, the same being provided with the usual fuel door 2,

ate 3 and smoke outlet 4.

45 The top of the stove or furnace is adapted to be closed by a hood 5 which is gradually reduced in transverse area toward its upper end and merges into a pipe 6 opening into a blower casing 7 Any suitable form of 50 blower, not shown, is arranged within the casing and is adapted to be driven by a shaft 8 journaled on a frame 9 secured to the hood 5 and suitably braced as shownjat 10.

A sheave 11 is connected to the shaft 8 55 and receives motion through a belt 12 from a smaller sheave 13 secured on the drive shaft 14 which is journaled on frame 9 and may be actuated in any desired manner, as by means of a crank 15. A large sheave 16 is secured to shaft 14 and transmits motion through a belt 17 to a small sheave 18 secured to a shaft 19 journaled on the frame 9. This Shaft 19 carries a blower, not shown, which is located in a casin 20, said blower casing having an outlet plpe 21 extending therefrom and which cancbe of any length desired.

The blower casing 7 has an outlet pipe 22.

provided with a valve 23 which can be opened by means of a handle 24, this valve being in the form of a damper or of any other desired construction. A flexible tube 25 may be extended from the pipe 22 and this tube may be provided with a nozzle 26 which, as shown in Fig. 1, is preferably cylindrical and has a collar 27 around its inner end.

Handles 28 may be connected to the hood to facilitate the lifting of the same.

A shaft 29 is extended diametrically across the lower portion of the hood and is provided, at one end, with an actuating crank 30 while an intermediate portion thereof carries a crank 31. Said crank 31 engages the bail 32 of a pan 33 located in the stove or furnace 1. A clip 34 is connected to the outer side of the hood 5 and is adapted to engage the crank 30 to hold it out of its normal or depending position.

In using the apparatus herein described, fuel is placed on the grate 3 and ignited, the hood 5 being positioned upon the stove or furnace. Sulfur is placed in the pan 33 and the crank 30 is swung downwardly so that crank 31 will lower the pan 33 onto the fuel where the sulfur will be ignited, thus forming sulfur dioxid. The tube 25 is extended into the room to be fumigated after which the crank 15 is rotated to cause the blowers within the casings 7 and 20 to be actuated. The blower in casing 7 will suck the fumes of carbid dioxid out of the hood 5 and force them through the tube 25 to nozzle 26 and thus into the room to be fumigated. If the person using the apparatus is located in the room being fumigated, fresh air may be supplied to him through the pipe 21 from the blower in casing 20.

By providing a nozzle such as shown at 2627, rodents can be exterminated by I thrusting the nozzles into the burrows or holes, the collar 27 serving to prevent lea k age around the nozzle. T us the fumes w1ll forcibly expelled into the burrows or holes and the rodents suffocated. When it is desired to fuinigate straw or like materials, a nozzle such as shown in Fig. 4 may be employed, this nozzle including a tubular member 35 having a pointed end whereb it can be inserted readily into the material to be fumigated, said end being indicated at 36. Apertures 37 are formed Within the peripheral portion of the nozzle through which the fumes will escape. The supply of fumes to the nozzles can be quickly cut off by means of the valve 23.

By lifting the pan 33 05 of the fuel, additional This pan can be elevated by means of the crank 30, which when swung into engagement with the clip 34, will be held in elevated position.

fuel mayv be placed thereunder.

fumes enerated by the heating of the contents of the receptacle.

In testimony that I claim the foregoing.

as my own, I have hereto afiixed my signa ture in the presence of two witnesses.
